    Abstract: A fuel injector comprises a pressurization section defining a variable-volume pressurization chamber. A nozzle section has a longitudinal bore, a nozzle chamber, an orifice and a nozzle valve. The nozzle valve is slides in the longitudinal bore between a first position that blocks fluid communication between the nozzle chamber and the orifice, and a second position that opens fluid communication between the nozzle chamber and the orifice. A check valve is between the pressurization chamber and the nozzle chamber. The check valve comprises a housing comprising an upper portion, a lower portion and a middle portion. The housing defines a check valve chamber. A valve member in the check valve chamber hydro-pneumatically moves between an open position that allows fluid communication from the pressurization chamber to the nozzle chamber and a closed position that prevents fluid communication from the nozzle chamber to the pressurization chamber.

    Abstract translation: 燃料喷射器包括限定可变体积加压室的加压部。 喷嘴部分具有纵向孔，喷嘴室，孔口和喷嘴阀。 所述喷嘴阀在所述纵向孔中在阻止所述喷嘴腔和所述孔之间的流体连通的第一位置和打开所述喷嘴室与所述孔之间的流体连通的第二位置之间滑动。 止回阀位于加压室和喷嘴室之间。 止回阀包括壳体，该壳体包括上部，下部和中部。 壳体限定止回阀室。 止回阀室中的阀构件在允许从加压室到喷嘴室的流体连通的打开位置和阻止从喷嘴室到加压室的流体连通的关闭位置之间进行液压气动移动。

    Abstract: A fuel injector has a plunger to which a piston applies force to inject fuel and to which fuel at fuel rail pressure is also applied to provide additional injection force. The fuel which provides the additional force is recovered to increase operating efficiency.

    Abstract: A dual-mode fuel injector has an internal part containing a variable volume chamber space which fills with fuel at common rail pressure and a plunger which is operable to force fuel out of the variable volume chamber space and to be injected out of the nozzle through the injection orifices at amplified pressure greater than common rail pressure. The plunger and the internal part have respective surfaces which come into mutual abutment during filling of the variable volume chamber space with fuel at common rail pressure and which, when in mutual abutment, create a seal which seals fuel in the variable volume chamber space against escape from the variable volume chamber space past the seal.
